Specification of Letters Patent.

Patented April 14, 1908.

Application filed April 12, 1907. Serial No. 387,725.

To all whom it may concern:

Be it known that I, HENRY B. UNRUH, a citizen of the United States,residing at Great Bend, State of Kansas, have invented certain new anduseful Improvements in Railroaddlails, of which the following is aspecification.

My invention relates to railroad rails and more particularly to theshapes of the ends of the rail members whereby the'ends of adjacent railmembers may be interlocked to form a substantially unbroken continuousrail or track. I

The primary object of the invention is to provide a rail member which isarticularly simple in construction and big ly efficient in use.

Other objects ofthe invention will be 'appreciated from the device ashereinafter described.

The invention is illustrated in the accompanying drawings in whichFigure 1 is a perspective view of one rail member. Fig. 2 is a plan viewof the rail joint formed with my improved rail members and Fig. is atransverse sectional view of the same. 0 I

The invention includes generally a joint in j which each rail member isprovided with a pocket or recess extending vertically through the head,web and base thereof, a second pocket or recess extending verticallythrough the web and base, a third recess extending through the baseonly, and co-acting shoulders or surfaces adapted to interlock with thewalls of similar recesses in a companion rail member. As will beunderstood; the coacting ends of adjacent rail members are formedcompiemental to each other.

As herein illustrated, the end of each rail member is formed by areduced extension 1 of substantially one-half the full width of therail, which extension has a flat perpendicular side 2 located in thevertical plane of the center of the rail, which side terminates 'at itsrear end in and constitutes one side wall of a substantially ti-shapepocket or recess 3, the other wall of which, designated 4, is formed bythe beveled end of the part of the rail at one side of the reducedextension. The pocket 3 extends vertically through the head, web andbase of the rail member. The front end of the extension 1 is beveled asindicated at 5, the latter surface extending at substan tially the sameangle or in parallelism with Each extension 1 termmates in a tongue 6which is provided with a bevel front edge 7 and an upper surfacearranged in the-horizontal plane of the bottom of the head of the railand is further provided with an outer face substantially in the verticalplane of the outer side of the head of the rail and an innerface'substantially in the vertical plane of the outer face of theusualweb,

the latter face, designated 8, formingwith the part of the surface 5,below the head of the rail, a substantially V-shape ocket 9. One end ofthe base flange of the rai member is substantially in transversealinement with or terminates at the base of the bevel 7 of the tongue 6and the other flange of the rail substantially the vertical planes oftheouter side of the rail l1eads,a s described, and'the.

tongues 6 form continuations of these thickened parts. I

,The structure defined includes, as will be noted, three recesses orpockets substantially ofV-shape, the innermost of theseipockets,

desi'nated 3, extending vertically through the read, web and base of therail member, the pjoclket 9 extending through the web and base of therail and the pocket 10 extending through the base of the rail memberonly. The structure also provides three substantially V-shape noses, orprojections, adapted to interlock with recesses, corresponding to thosedescribed,jin the end of the adjacent rail member. i

The adjacent ends of two rail members are 'oined by a relativelongitudinal movement of the two with the parts held in proper re ister.

n the completed joint the nose on the end of the tongue 6 fits withinthe recess 10, in the companionrail member, the nose onthe extension 1fits within the recess. 3 and the nose on the web and base formed in artby the side 4, fits within the pocket 9 w lo the bevel side 4 of therail-head co-acts with the similarly bevel surface 5 on the co-actingrail member.

To bind the arts securely suitable transversely exten mg bolts 11 areprovided which may have associated therewith suit- I able nut locks. Tofurther hold the parts together, a chair 12 is preferably provided foreach joint. This chair consists of a substantially channel plate whichextends between and is secured to adjacent ties. The upper flat surfaceof the plate provides a support for the base of the rail and the flangesat the side of the chair abut against the outer edges of the base of therail to prevent the rail members spreading transversely.

I claim:

1. A rail member having a recess extend ing vertically through the head,web and base thereof, a second recess in advance of the first extendingthrough the web and base of the rail member, and a third recess to therear of the first extending through the base of the rail only.

2. A rail member having a recess extending vertically through the head,web and base thereof, a second recess in advance of the first extendingthrough the web and base of the rail member, a third recess to the rearof the first extending through the base of the rail only, andinterlocking projections on the rail member adapted to fit withincorresponding recesses in a co-acting rail member.

is. A rail member, having an extension at the end thereof havin a flatperpendicular face located substantially in the vertical plane of thecenter of the rail, and a substantially \I-shape nose at its forwardend, said rail'member having a recess at the rear rail, a tongueextending forwardly from the end of the extension below the head of therail terminating in a substantially V-sha e nose and having a flat sidein snbstantia l r the vertical plane of the outer side of the rail weband forming with the nose of the extension a substantially V-shaperecess, one of the flanges of the rail terminating at the base ofsaidnose of the tongue and. the other of the rail flanges extending fromthe Web a distance to the rear of the first named recess and beingprovided with a recess adjacent the rail web.

4. In a rail joint, two rail members, each having two correspondingbevel surfaces, one located in advance of the other on the rail end ofsaid extension of the full height of the head co-acting with likesurfaces on the other I ra1l member, two corresponding bevel surfaces,one located in advance of the other on' the web co-acting with likesurfaces on the other rail member, and a rentrant and salient bevelsurface on the base with complemental surfaces on the other rail member,substantially as described.

In testimony whereof, I have hereunto signed my name in the presenceof'two attesting witnesses at Great Bend, this 29 day of March, 1907.
